DNG-2300 – Noise generator

It is well known that sound penetrates through walls, doors, water, windows, and other structures, as well as through voids, cavities, and ventilation shafts. This property of these materials allows conversations taking place in rooms to be intercepted from outside using high-sensitivity contact microphones (electronic stethoscopes), window laser systems, or ordinary microphones.

Wall contact microphones can pick up vibrations from plumbing, structures, walls, windows, doors, floors, ceilings, and much more. The eavesdropping device can be located in an adjacent room or even several floors or rooms away; it can be attached to a wall, pipe, or other structural elements. Cavities, such as ventilation pipes, shafts, or other voids, can be used to intercept sound from an adjacent room using ordinary microphones. Window laser systems are capable of “reading” conversations from a room by sending visible or invisible infrared beams onto the glass and extracting sound vibrations from the reflected beams.

The DNG-2300 Generator, equipped with its own vibration emitters (transducers) and acoustic emitters (speakers), counteracts all the aforementioned methods of eavesdropping by creating powerful, unfiltered interference on the building structure and in its voids.

Features

• Powerful protection against leakage for all types of vibroacoustics by transmitting unfiltered noise onto surrounding structures and into cavities.
• Suppresses wall contact microphones, window laser systems, and wired microphones inside walls, cavities, and ventilation shafts (ventilation pipes).
• It is a key part of the protective system, which also includes wired vibration emitters and acoustic emitters.
• White noise generation – the output interference is uniformly distributed across the spectrum of the human voice.
• Has 3 independent output channels: 2 for vibration emitters and 1 for acoustic emitters.
• All 3 channels can be regulated separately by level.
• Each TD2300 vibration emitter channel can power up to 12 transducers installed on heavy or solid structures (concrete/cement/brick), and up to 24 transducers on light structures (glass, pipes, drywall, wood).
• The acoustic emitter channel can power up to 12 speakers.
• The input for controlling the acoustic emitter muting mode allows the user to temporarily disable the speakers.
